CATTLE-G UARD.

SPECIFICATION forming part of Letters Patent No. 431,119, dated July 1, 1890.

Application filed March 27, 1890- Serial No. 345,495- (No model.)

To all whom it may concern:

Be it known that I, PARKER MERRILL, a citizenof the United States, residing at St. Louis, in the county of Gratiot and State of Michigan, have invented certain new and usefui Improvements in Railway-Surface Oattle-Guards, of which the following is a specification. I

This invention and improvement relates to the surface cattle-guard in a patent of mine dated October 15, 1889, No. 412,967. In said patent a series of rods that are in two pieces and connected by turn-buckles are shown between the rails supported above the ties by transverse beams, and a like series on the outside of each rail.

The particular object of the present invention and improvement is to construct the said series of bars so that each bar shall be of one piece and to construct the entire guard so that it shall be in four sections, two sections between the rails and one section outside of each rail. Economy of material and more desirable attachments of parts may be named among the advantages of thus constructing the guard, as compared with what is shown in the above-named patent.

In the drawings forming a part of this specification, Figure 1 is a plan showing the rails C of the track and the ties F and one of the above-mentioned foursections in position. Fig. 2 is a section on line 3 Fig. 3 broken perspective of a lettered detail.

Referring to the lettered parts of the drawings, s s are the separated rods. Each of the four sections has two or more transverse beams A A. The rods 3, provided with hooks at each end, are attached to the terminal beamsbybeing hookedinto holes e, as shown in Fig. 2. The hole 6 is best shown in Fig. The transverse beams A are formed into shape from strips of metal and rest upon the upper surface of the ties, one being placed at the middle of each section, upon which the bars 8 rest and to which they are secured by staples t.

D D are longitudinal side bars, two for each one of the four sections. They are bolted to the ends of the transverse beams A with bolts E, that hook into holes a, that are in each side at each end of the beams Av is a The bolts E may be hooked into holes a from either the outside or the inside of beams A. The side bars D may be bolted to the ends of beams A at the base or top or middle of said beams, and the ends of said side bars are to be bent down to the tie when they are bolted to the ends of said beams A at their top or middle height. The side bars D are turned or swaged down flat at'each end and provided with holes h for spikes to secure them to the ties, all of which is best shown in Fig. 3. In putting the guard together the side bars D are first bolted in their position to beams A. The bars .9, which are of a length tohook into the holes ewhen the centerbeam is sprung or forced down a little lower than the terminal beams, arethenattached. *hencompletethe section is put in place, the center beam resting upon a tie; The side bars at one end of the section are next spiked down to a tie. The opposite end of the section will then be a little above the tie, which, when that end is drawn down with spikes, will bring a strain or tension on the bars 8. All four of the sections required for a guard are to be constructed in the same manner as the one shown.

Having thus described myinvention, whatI claim, and desire to secure by Letters Patent, 1s

1. In a railway-surface cattle-guard comprising sections between and outside the rails of the track, the combination, in each section, of two or more round-top transverse metal beams, with a series of rods provided with hooks at each end that are hooked into the upper surface of the terminal beams, and two side bars bolted to the ends of all the beams in said section, the ends of said side bars being spiked to the upper surface of the ties supporting the terminal beams, substantially as set forth.

2. In a railway-surface cattle-guard having sections between and outside the rails, the combinationof four sections that are alike and interchangeable, two sectionslying between the rails of the track and one 011 each side of it, substantially as set forth.

PARKER MERRILL.
